i u n:PORTABLE FIREPROOF BUILDING.

Application filed Aprii 4, 19123.. serial- No. 'ezassa This invention relates to metallic structures, and particularly to relatively Asmall' portable metallic buildings.

One of the objects of this invention is to' provide a building of this character which does not require studding for itsA support nor any vertical columns or beams but which is so `constructed that the roof is supported entirely by the compound metallic sheet which is used for the side walls of the building.

A further object is to -provide a building of thischaracter in which the parts may be readily assembled or disassembled whenever desired and which, therefore, is particularly suitable for portable houses for use p by campers, tourists and wherever portable buildings are desired.

A still further object is to provide a building of this character in which the walls and roof are formed of two sheets of material, one of said sheets being corrugated and with anl interposed layer of fire-proof material between the sheets.

Another object is to provide a device of this character in which one of the sheets forming the compound wall is bent so as to particularly strengthen the wall and render it rigid. l

Other objects haveto do'with the details of construction and arrangement of parts as will appear more fully hereinafter.

My invention is illustrated in the a'ccomf panying drawings, wherein Figure 1 is a perspective sectional view of a building constructed in accordance with my invention, the parts being broken away;

Figure 2 is an end elevation of the building shown in Figure 1;

' Figure 3 is a section on the line 3-3 of Figure 1;

Figure 4 is a section on the line 4-4 0f Figure 2;

Figure 5 is a section on the line 5 5 of Figure 2;

Figure Gis a section on the line 6--6 of Figure 1;

Figure 7 is a fragmentary transverse section through vthe roof but showingV a modified form of crown or capping; I Figure 8 is a fragmentary perspective view of o-needge of one of the siding plates.

Referring .to these drawings, it will be seen that I have illustrated a rectangular vbuilding having a gable roof, though I do not `wish to be limited to this particular shape. This building is formed of wall sections, as clearly illustrated in section in FigureG and designated A. As illustrated,

there aretwo of these Wall sections on each long side of the building and one wall seetionB at each end of theV building. The

` wall sections A each consist of an inner and outer layer 'or thickness of sheet metal, designated y10 and 11, the outer layer being corrugated vertically and being formed of one or more lengths of material, through preferably one length of material is to be used. If more than one length of material 1s used, the margins of the material are overlapped and one sheet fastened to the other.

A Disposed within the vertically corrugated sheet 1() is a plain sheet of material 11. This sheet at its lower end is inwardly bent, as at 12, then outwardly bent, as at 13, and then downwardly bent, as at 14. The flange thus formed is adapted to rest upon the sills D, which in turn supports the floor board C. The upper margin of the inner` sheet 11 is outwardly flanged, at as 15, then inwardly bent, at at 16, against the flangev 15 and then downwardly bent, asat 17. The outer'slieet 10 extends below the flange at the lower edge 14 ofthe inner sheet 11 and these inner and outer sheets may be held together in any suitable manner as, for instance, by rivets assing through the two sheets, the rounde or smooth heads of the rivets being on the inside face of the wall.

Disposed between the outer sheet 10 and the inner sheet 11 is a layer or sheet 18 ofre-proof material such as sheet asbestos. I do not wish to be limited, however, to the use of asbestos, as other lire-proof materials may be disposed in a layer between these tw'o sheets 10 and 11 and it is within my invention to use any fire-proong layer which I may desire to use.

As will be seen from Figure 8, one end of the sheet 10 is angularly bent, as at 19, and the flange 17 at its end extends over the sheet 10 and is angularly bent, as at 20` so as to reinforce this fiange 19. The gable ends B of the struct-ure are of the same character as the sides A, that is formed with an outer vertically corrugated sheet and an inner plain sheet held together by bolts and `having an intermediate layer of fire-proof material. The roof sections are also formed of an inner sheet 21 which is plain or flat and an outer sheet 22 which is corrugated in a direction from the ridge of the roof to the eaves thereof, and disposed 'between these two sheets is the intermediate layer 23 of fire-proof material, such as asbestos, previously referred to.

This root' is composed of sections, the sections meeting at the ridge of the roof and extending beyond the walls A and B. The inner sheet 2l of each roof section has at its inner edge an upwardly .extending flange 24 This flange is bent downwardly upon itself, as at 25, and then extends downward along the upper face of the sheet 2.1 so as to reinforce this upwardly extendlng flange and make it of double thickness (see Fig. 2). The lower edge of this inner sheet is folded back upon itself, as at 26, and the corrugated sheet 22 rests upon the upper face of this return reinforced portion 26 and also extends over the returned portion 25. The end of the roof section which projects beyond the gable is also turned back upon 1 tself or reinforced, as at 27. The roof` sections are adapted to be held to the wallv sections by bolts 28 which extend downward through the roof sections and through the projecting flanges 15 of the wall sections. The inner edges of the. roof sections, as before remarked, are bent so as toiform a flange 24 and acrest 29 is adapted to be used therewith, this crest being made `of sheet-metal bent into an arrow shape `or triangular form in cross section and having a. downwardly extending supporting web 30 disposed between the flanges 25 and bolted at intervals thereto.

I do not wish to be limited` to this, Vas it is obvious that, as illustrated in Figure 7, a longitudinally extending plate or strip 31 might be disposed between these flanges 24 and be bolted thereto. This strip of bar is preferably of steel 21/2 x ys or may be of any suitable length and permits the use of an ordinary ridge capping 32 whose skirts are corrugated and extend over onto the corrugated upper face 22 of the roof. Any suitable crest or rigid piece may be used in connection with this roof and supported by the flanges 24.

As illustrated in Figure l, I have formed the building in two parts with intermediate walls E. These intermediate walls do not have a corrugated facing but are flat walls which are disposed against each other and between these intermediate walls E is a layer of lire-proof material 33. Bolts pass through these two abutting walls and detachably hold these walls in engagement with each other. These walls are of the same shape as the gable walls B but are notched, as at 34, for the passage of the web 30 or the bar 31 of the rigid piece or crest. Both of these walls E are flanged at their lower tends, as at 35, these flanges corresponding to the flanges 12 on the side and end walls. x

If a building formed in two sections is used, then the roof is preferably formed in two sections also, that is the inner edgesi of ,the sheet 21 are u wardly turned or angled, as at 36, and olted together by bolts 37, and cap pieces 38 being also bolted to these flanges and extending down over the abutting facesof the flanges' so as to vertically corrugated sheets l0 of the side. walls, which I find will resist considerable downward pressure when braced and held in place by the roof sections. The flanges 12 mayV be perforated at intervals for the passage of nails, screws or bolts whereby the structure may be held down to the sills D or the flooring board C. The roof sections extend beyond the side and end sections of the structure so as to completely Shed water. The structure may be readily put up and because of the fact that,` it is built in sections may be readily handled and shipped. I design to build the structure in units, each unit being 10 X 12, and join two units up to make a larger building. These structures may be used as garages, campers cabins, and for any purpose for which a portable house is necessary or desirable.

1. A portable house, the walls of which are formed of side and endsections, each section consistingl of an inner fiat sheet of metal and an outer vertically corrugated vsheet of metal, the sheets being bolted to each other, the inner sheets of the'sections forming the side and end walls having at their upper ends outwardly projecting anges extending downward over the top edges yof the upper sheet, to afford a support for a roof.

2. In a metallic building, a wall section composed of an outer sheet of vertically corrugated metal 4and an inner sheet of fiat metal, the inner sheet at its upper ends being outwardly flanged over the top of the outer sheet and then returned uponitself and extending downward between the inner and outer sheets, to thereby a'ord a support for a roof.

3. A portable metallic building of the character described including twoA units, each unit having opposite side walls and end walls, one of said end walls and both side walls having outwardl lprojecting flanges at their upper ends, w ei'eby to sup ort a 5 roof, the two units of which the buil ing'is composed having the remaining end walls abutted against each other, and means joining said end walls. A

4. In a metallic building formed of sec- 10 tions, each section including a flat inner sheet of metal and an outer vertically corrugated sheet, the outer sheet extending below the inner sheet and the inner sheet havingi its lower end inwardly flanged whereby the l5 outer corrugated sleet may extend down'over the sill of a sub-structure and the ange A may rest upon the sill thereof. Y p

5. In a metallic building, a wall section composed of inner and outer sheets of metal, the outer sheet extending below the inner 20 sheet to form a skirt and the inner sheet being inwardly-flanged at its lower edge, s'aid inner ksheet at its upper end being outwardly flanged over -the top ofthe outer sheet to provide a roof-supporting means and the 25 l sheets being enga ed with each other.
